          Platform: x86-64 (AMD64)

Xorg.0.log

I've been seeing occasional hard locking of X when I change the size of my
video player from windowed to full screen or from full screen to windowed. 
Here's my setup:

Debian Squeeze AMD64
Kernel 2.6.30-rc5 (self compiled)
Xorg 7.4 (self-compiled)
Gnome 2.26.1 (debian packages)
Totem 2.26.2 (debian package)
radeonhd (I git pull every 2-3 days.)
drm (native, built into kernel 2.6.30)

Two 1920x1200 panels over DVI
DVI-I_1/digital is Left Panel
DVI-I_2/digital is Right Panel

I've been using randr to disable the left monitor when I watch videos. This
seems to be a necessary condition for the bug.  I see the bug when running
totem on the remaining right display.  X locks hard when totem transitions
between full screen and windowed mode.  It happens on both directions.  All
keyboard input is ignored.  I have to ssh in and kill X.  It's always at 100%
cpu utilization.

This doesn't happen on every transition between windowed and full screen but it
happens often enough.

I've been using the power switch to disable my left monitor.  I want to verify
that the bug happens only when randr is used to disable the left screen.  It
has been proven true so far.

I have tried the "radeon-test-ring.patch" from Bug 21849.  It didn't help.  The
logs attached were produced wile running a kernel with that patch.
